External Node Provider
--------------------------
Ray also supports external node providers (check `node_provider.py <https://github.com/ray-project/ray/tree/master/python/ray/autoscaler/node_provider.py>`__ implementation).
You can specify the external node provider using the yaml config:
.. code-block:: yaml
provider:
type: external
module: mypackage.myclass
The module needs to be in the format `package.provider_class` or `package.sub_package.provider_class`.
Additional Cloud providers
